The Hong Kong lawyer for a group of refugees who sheltered former NSA contractor Edward Snowden four years ago says the southern Chinese city's immigration department has rejected their asylum requests.

Snowden hid out in Hong Kong for two weeks in June 2013 after he leaked documents revealing extensive US government surveillance. His whereabouts were a mystery during that time.
